摘要： Systems for positioning a functional element, such as an optical lens, include a housing, a primary guide pin coupled to the housing, a functional group that includes the functional element, and a vibrational actuator assembly. The functional group is movably coupled with the primary guide pin and includes a first friction surface and a second friction surface. The first and second friction surfaces are oriented relative to one another at one of an obtuse angle and a straight angle. The vibrational actuator assembly is substantially registered relative to the housing and includes a first drive element and a second drive element. The first drive element is configured to interact with the first friction surface and the second drive element is configured to interact with the second friction surface. The vibrational actuator assembly operates to translate the functional group. Some embodiments include position sensing elements configured to detect position(s) of the functional element(s), and control system(s) configured to operate the actuators based on feedback from the position sensing system(s).

摘要： Embodiments of the present invention relate to systems and methods of position sensing that use a sensing target with a pattern of features thereupon, and to positioning modules and systems that position functional elements using such position sensing systems. A position sensing system includes an encoding module and a processing module. The encoding module has an active encoding region through which the sensing target is configured to move. Further, the encoding module is configured to generate a signal based on a portion of the sensing target within the active encoding region. The active encoding region has a dimension greater than the average critical dimension of the pattern of features. The processing module is configured to convert the signal generated into a position data based on an input range condition and an initial position condition.
